Abstract

A fastening system for assembling appliances, in particular electrical appliances, comprising at least one profile rail provided with openings and comprising at least one quick-fastener which has a body in which at least one internal thread is formed, is characterized in that the body has over its length (L) at least two spaced-apart internal threads, wherein, in an exact position of the quick-fastener relative to the profile rail, each of the internal threads is brought into alignment with one of the openings of the profile rail, and in that a clamping blade having the same length L as the body is attached to the body, which clamping blade forms between it and the body a gap for receiving the profile side and holds the body against the profile rail by friction.

First claim

What is claimed:

1. A fastening system for assembling appliances comprising at least one profile rail furnished with openings and at least one quick fastener that has a body in which at least one internal thread is formed, wherein the body has at least two internal threads spaced apart from each other along its length (L), wherein each of the internal threads is brought into alignment with one of the openings on the profile rail in an exact position of the quick fastener with respect to the profile rail, and in that a clamping blade having the same length L as the body is attached to the body, forming an open space between itself and the body to receive the profile rail and holding the body by friction to the profile rail;
wherein the body has a slot for each internal thread in which a nut is positioned secured against rotation.

2. The fastening system according to claim 1 , wherein the clamping blade is attached flexibly to the body.

3. The fastening system according to claim 1 , wherein the body is configured essentially rectangular.

4. The fastening system according to claim 1 , wherein the body has a chamfered edge to assist in placing it onto the profile rail.

5. The fastening system according to claim 1 , wherein the nut is a cage nut which sits in its assigned slot to prevent loss.

6. The fastening system according to claim 1 , wherein the clamping blade, in a precise position in the transverse position extends over the openings in the profile rail.

7. The fastening system according to claim 1 , wherein the clamping blade has openings that are oriented in alignment with an assigned internal thread on the body.

8. The fastening system according to claim 1 , wherein the body and the clamping blade are located relative to one another in such a manner that an open space is formed between them narrowing towards an open longitudinal edge of the clamping blade.

9. The fastening system according to claim 1 , wherein the body and/or the clamping blade has means to increase the friction to the profile rail.

10. The fastening system according to claim 9 , wherein the means to increase the friction to the profile rail are provided in the form of fluting.

11. The fastening system according to claim 1 , wherein the clamping blade is L-shaped in cross-section, wherein the length (a) of a first leg is greater than the thickness (d) of the profile rail in the area of the openings.

12. The fastening system according to claim 11 , wherein the length (b) of a second leg is selected in such a manner that the clamping blade at least partially overlaps the internal threads of the body.

13. The fastening system according to claim 1 , wherein the clamping blade has at least one recess which exposes markings on the profile rail when in a precise position with respect to the profile rail.

14. The fastening system according to claim 1 , wherein the body and/or the clamping blade has at least one nub projecting into the open space which retains the quick fastener in a precise position with respect to the profile rail in which the nub is accommodated in a recess or an opening in the profile rail.

15. The fastening system according to claim 1 , wherein the profile rail is part of an assembly array in which the openings are equally spaced towards the profile rail and in which three consecutive openings define a unit of height for a rack frame.

16. The fastening system according to claim 1 , wherein the quick fastener has a potential equalization element which has, or consists of, an electrically conductive material and both extends into the open space and makes electrical contact with the internal thread.

17. The fastening system according to claim 16 , wherein the potential equalization element extends above a surface of the clamping blade that faces away from the open space.

18. The fastening system according to claim 16 , wherein the clamping blade consists of a first material and the potential equalization element of a second material, wherein the first material is softer than the second material, wherein the potential equalization element, with a supporting section that turns into a contact tip, projects into the open space so that the contact tip is pushed through the surface of the clamping blade facing away from the open space when the quick fastener is placed on the profile rail.

19. The fastening system according to claim 18 , wherein the contact tip of the potential equalization element is enclosed by the first material of the clamping blade secure against contact and is pushed out of the clamping blade when the quick fastener is placed on the profile rail.

20. The fastening system according to claim 1 , wherein the quick fastener has a potential equalization element that has, or consists of, an electrically conductive material and projects into the open space so that when placed on the profile rail an electrical contact is created with the profile rail by way of the support element, and the contact tip makes electrical contact through the surface with an additional component, in particular an electrical appliance.

21. The fastening system according to claim 1 , wherein the body is formed of plastic and the clamping blade of a metal, wherein the clamping blade is a single piece and connected permanently to the body and is preferably molded into the body.

22. The fastening system according to claim 21 , wherein the clamping blade has at least one contact spring on its second leg, taking the form of a push-through and projecting into the open space for the electrical contact of the profile rail.

23. The fastening system according to claim 21 , wherein the clamping blade has at least one contact spring on its surface facing away from the open space, taking the form of a push-through for the electrical contact with an electrical appliance.

24. The fastening system according to claim 1 , wherein the quick fastener is provided as continuous material, on rolls or in bar form with a plurality of internal threads, wherein the body of the quick fastener is divided into housing sections identical or differing in length that have a specific number of internal threads in each case and wherein the housing sections are connected by predetermined breaking points.

25. The fastening system according to claim 1 , wherein several quick fasteners are disposed along a connecting strip cut to length as required while retaining the spacing or a whole-number multiple of the spacing between the internal threads.
